Abstract
A twin laser camera unitary assembly for a robot processing tool is disclosed. The assembly has a housing having a front wall defining an upright U-shaped channel into which a tubular portion of the tool is laterally insertable. A mounting support attaches the housing relative to the tool in operative position. Twin laser range finders are respectively mounted in the housing on opposite sides of the U-shaped channel in a symmetrical in-line arrangement with respect to the tool. A controller mounted in the housing is configured to receive robot control signals, operate laser projectors and process image signals produced by imagers of the laser range finders so that joint and bead position and geometry signals are produced in a robot reference frame. The assembly is designed and protected for use in industrial processes such as robotic laser and arc welding and sealant dispensing.
